PAPER-GAGE.

SPECIFICATION forming part of Letters Patent No. 242,067, dated May 24, 1881. Application filed October 13, 1880. (No model.)

To all whom it may concern Be it known that I, RICHARD SMITH, of Sherbrooke, in the county of Sherbrooke and Province of Quebec, Canada, have invented certain new and useful Improvements in Paper-Gages, which improvements are fully set forth in the following specification, reference being had to the accompanying drawings.

The object of my invention is to provide an instrument for readily ascertaining the thickness of paper and similar materials by means of the combination of a Series of pivoted levers, links, and toothed wheels with a pair ofreceiving-jaws and indicator with supplementary pointer.

. Figure l is a front elevation of the instrument, showingpart of the cover removed; and

Fig. 2 is an end elevation of the same.

F is the frame or body of the instrument, having a removable cover, 0.

J is an adjustablejaw, adjustable by means of the set-screws, and held in its proper position in the grooveq of the frame F by means of the tightening-screw s The spindle S, carrying the registeringjaw J is guided by the lugs l l, forming part of the frame F, and is raised by means of the pivoted handle H, for the purpose of introducing the material to be measured between the jaws J J the spring G serving to bring the registering-jaw to its proper position when pressure is removed from the handle.

. p p p p p 19 are knife-edged pivots, of whichp is attached to the registering-jawJ 3 5 p and p to the lever L, p and p to the frame F, and p to the lever L The linlrK communicates the motion of the registering-jaw J 2 to the lever L, havingits fulcrum at 19 which,

in its turn, communicates the motion to an increased extent, by means of the link K to the J to be shown b the reatl finer-eas d move- 0 meut of the pointer R around the dial D.

V The case A, inclosing the dial D, is provided with a supplementary pointer, It, and is so attached to the frame F as to be revoluble about the dial, by which means the supplementary pointer B may be placed at any desired point of the graduated scale for purposes of comparison.

The spring G is for the purpose of assisting the Spring G in bringing the respective parts -to their normal position.

I claim as my invention- The combination, in a paper-gage, of the adjustable jaw J, the movable jaw J controlled by the spring G, and connected at its inner end with levers L L and quadrant-rack Q by links K, K and K the pinion-wheel P, having on its spindle the index-pointer R, the dialplate D, and case A, with its Supplementary pointer R all constructed substantially as and for the purpose described.
